Flower-like molybdenum disulfide/cobalt ferrite composite for the extraction of benzotriazole UV stabilizers in environmental samples.

Benzotriazole UV stabilizers (BUVSs) are a class of emerging contaminants of concern; the development of rapid and convenient monitoring method for these trace-level pollutants in waters is of crucial significance in environmental science. Here, a novel magnetic flower-like molybdenum disulfide/cobalt ferrite nanocomposite (MoS/CoFeO) was synthesized by hydrothermal reaction. Compared with the conventional FeO-based magnetic composites, the proposed material just required a minimum consumption of Co/Fe towards the equivalent of MoS while providing superior magnetization performance.
